Two-inch baffles come standard, with optional baffles available. They use a constant velocity baffle design for improved performance, and the baffle also uses a high-density bonded e-class sleeve and stainless steel mesh, which contributes to a better acoustic quality.
Though the baffles work to reduce the tone and volume, they also contribute to the power gains from the mufflers, which are among the highest in the industry. And on models that use a cross-over on the stock system, the Cobra Slip-ons include a similar OEM-style balance tube to increase overall performance. They fit the stock head pipes on all models as well as the new Cobra PowerPort Duals and the Cobra True Dual head pipes for Baggers.
